how to handler with custom alert action

[amasahara]

i try to create an custom alert with 3 button like this
`eventController.saveDanhMucDVKT
.map { table.items }
.flatMapSingle { lstDMDVKT ->
val dialog = Alert(Alert.AlertType.CONFIRMATION, "Lựa chọn hình thức lưu dữ liệu",
ButtonType("Save", ButtonBar.ButtonData.YES),
ButtonType("Save and delete", ButtonBar.ButtonData.OK_DONE),
ButtonType("Cancel", ButtonBar.ButtonData.CANCEL_CLOSE))

                //save but not remove old data
                dialog.toMaybe().filter { it == ButtonType.YES }
                        .map { lstDMDVKT }
                        .flatMapSingle {
                            danhMucDVKTController.createList(it)
                        }.toObservable().toSet()

                //save and remove old data
                dialog.toMaybe().filter { it == ButtonType.OK }
                        .map { lstDMDVKT }
                        .flatMapSingle {
                            danhMucDVKTController.delete()
                            danhMucDVKTController.createList(it)
                        }.toObservable().toSet()
            }.publish()`

but seem it not save data to database. which way i wrong

Did you actually subscribe to it or connect it?

[amasahara]

yes i has been do it same with your example, but when i debug, it not run into .flatMapSingle {
danhMucDVKTController.createList(it)
} and i don't know why

Here is my full code for alert dialog. but after i update new data into my database it always show dialog 2 times and when i restart this form it always show dialog again before run into form
`//handler save data into database
val saveData = eventController.saveDanhMucDVKT
.map {
table.items.toList()
}
.flatMapSingle { lstDMDVKT ->
Alert(Alert.AlertType.CONFIRMATION, "Lựa chọn hình thức lưu dữ liệu",
ButtonType("Thêm", ButtonBar.ButtonData.YES),
ButtonType("Lưu và xóa", ButtonBar.ButtonData.NO),
ButtonType("Bỏ qua", ButtonBar.ButtonData.CANCEL_CLOSE))
.toMaybe().toObservable()
.switchMap {
when {
it.buttonData == ButtonBar.ButtonData.YES -> danhMucDVKTController.createList(lstDMDVKT.observable()).toObservable()
it.buttonData == ButtonBar.ButtonData.NO -> {
danhMucDVKTController.delete().subscribe()
danhMucDVKTController.createList(lstDMDVKT.observable()).toObservable()
}
else -> Observable.empty()
}
}.toSet()
}.publish() //publish() to prevent multiple subscriptions triggering alert multiple times

    saveData.subscribe(eventController.savedDanhMucDVKT)

    //add data into datase
    eventController.savedDanhMucDVKT
            .map { Unit }
            .subscribe(eventController.refreshDanhMucDVKT)

    saveData.connect()`
